[TowerTalk] decoupling feedline from a dipole

[Jim Miller WB5OXQ]

I hear that decoupling the feedline can reduce noise so what is the best way to do to.  I have tried commercially made baluns in the past only to have them burn out at legal limit power levels.  Is a choke wound from the feedline like I made for my beam going to do the job or something else.  I am plagued by 10 to 30 db over s9 noise on 75 especially using an inverted v at 55'.  Noise seems worse on AM when no carrier is present than on ssb also.
